Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork panel for concrete and a formwork apparatus for forming a building frame. More specifically, the present invention relates to a concrete formwork panel and a formwork apparatus for forming a frame frame, which are suitable for use in forming beams and floor slabs of steel-framed reinforced concrete structures, such as high-rise buildings.

In general, the design of formwork for concrete pouring is related to shoring, and is sufficiently safe to withstand the load, taking into account the shape of the completed structure, dimensional errors, and formwork, and until the concrete structure is completed. It must be carefully designed so that nothing goes wrong.

The loads that formwork and shoring receive during construction include the weight of the formwork itself, the concrete notebook, workers, construction equipment, etc., the vertical load due to impact, wind pressure, slope, water pressure, and vibration during work. It is extremely difficult to construct formwork equipment that can sufficiently support these loads.

In conventional frame forming, plate-shaped formwork that supports the concrete in the beam section and plate-shaped formwork that supports the concrete in the floor slab section are arranged in the vertical and horizontal directions, and the formwork for supporting the beam is arranged vertically and horizontally. The floor slab is supported by form ties, columnar fixing members extending in the longitudinal direction, vertically and vertically extending end pieces, and lower joists extending in the longitudinal direction, and the formwork for supporting the floor slab is horizontally supported. Because it is supported by beams arranged in different directions, it has a large number of parts, a complicated structure, and poor workability during assembly and disassembly.

The reason why so many parts are required is that the strength of the plate-shaped frame itself is weak.

On the other hand, strong formwork panels have been developed in which the formwork and reinforcing members are integrally molded, but since the reinforcing members are integrally fixed to one side of the formwork, they can only be used on one side. Since it is made of iron, it is heavy and difficult to assemble, dismantle, and transport.

Furthermore, since the length, thickness, width, etc. of beams and floor slabs vary depending on each structure, formwork must be prepared depending on the size of the frame each time, which is not economical. It is.

Therefore, the object of the present invention is to provide a formwork panel for concrete that has high strength, can be used on both sides, has a small number of parts, is light in weight, and can be freely adapted to the length and size of the supported part. Use formwork panels for l-
An object of the present invention is to provide a formwork device for forming a skeleton.

In order to achieve this object, the present invention has a structure in which a locking part is provided on the side or end of a main body in which one or more hollow parts are formed along the longitudinal direction as a formwork panel, and a frame forming The formwork device is characterized in that one or more of the above-mentioned formwork panels and any number of mouth-shaped or nearly mouth-shaped formwork panels are alternately connected vertically and horizontally to a central formwork panel. be.

As shown in Fig. 1 and Fig. 2, in a steel-framed reinforced concrete structure, such as a high-rise building, the frame (3) such as the floor (1) and beams (2) is formed by pouring concrete. In this case, in advance, on the ground, a concrete burial connecting member (8) consisting of a support fitting (5), a cone (6), and a bolt (7) is attached to the top of the steel beam (4) along the longitudinal direction. The central formwork panel (9
) are connected, and the reinforcing member 00), which is a thick member, is suspended downward through bolts and nuts that pass through the locking part consisting of a long hole or a circle in the lower part of the formwork panel (9) in the center. ,
A reinforcing member 00), which is a large tension member, is horizontally connected to the reinforcing member 00) in a height and width adjustable manner, and a scaffolding device (12), such as a chain, is connected to the reinforcing member 00).

9) You can also hang it directly. Also, the central formwork member (9)
may be supported on the top of a support that stands up from the ground, and the connecting member (8) may not be used.

In addition, when the central formwork panel (9) is held, it is not necessary to assemble the end members 00) and scaffolding equipment 03) on the ground, and it is necessary to lay the concrete before pouring concrete from above the floor (1). It is also possible.

The central formwork panel (9) is removably connected to a cone (6) via bolts (7) passing through elongated, round, square holes, etc., and this cone (6) is connected to a support fitting (5). Through steel beams (

In this case, the cone (6) is plucked out from within the concrete and that portion is repaired.

At the bottom of the central A-frame panel (9), a beam support formwork panel (j4) is fixed in the vertical direction via bolts and nuts S, and a floor slab formwork panel 05) is fixed in the horizontal direction. These formwork panels (14) (t5) support the poured concrete along the longitudinal direction - formwork panels for beam support (141 is group panel 06) and horizontal panels (171) The outer surface of the vertical panel (t6) is supported by one or more reinforcing members (10) which are thick members, and the horizontal panel (1n is a reinforcing member 101 which is a large tension member).
